Kṣetra-kṣetrajñayor jñānam. This body and the kṣetra-jña, the owner and the occupier of the body. This subject matter we were discussing last night. It is very easy. I was explaining. Just like this apartment, we are occupying; therefore we are occupier, but we are not the owner. The owner is different person.
Similarly this body, there are two souls: the Supersoul and the individual soul. Jīvātmā, Paramātmā. Brahman, Parambrahman. Jīvātmā is Brahman constitutionally, because mamaivāṁśo jīva-bhūtaḥ (BG 15.7). The living entities, they are part and parcel of Kṛṣṇa, God. Therefore qualitatively, what is Kṛṣṇa, the jīva, living entity's also the same thing. There is no difference in quality.
But quantity there is difference. Paramātmā or Bhagavān, brahmeti paramātmeti bhagavān iti śabdyate (SB 1.2.11), all these three features of the Absolute Truth—Brahman, Paramātmā and Bhagavān—the ultimate cause is Bhagavān. As it is confirmed by Kṛṣṇa: brahmaṇaḥ ahaṁ pratiṣṭhā (BG 14.27). The Brahman effulgence, that is standing on Kṛṣṇa. Kṛṣṇa is the source of Brahman effulgence.
Just like the sun globe is the source of sunshine. Sunshine is very big, all-pervading, and sun appears to be located in some place. But which is important: the sunshine is important or the sun globe is important? Because the sunshine is emanating from the sun it has no independent existence. As soon as the sun disappears, there is no sunshine. So wherever there is sun, there is sunshine. Therefore sunshine is dependent on the sun.
